Well, Veronica Mars isn't available any longer unless you own the DVDs or want to purchase it - so...

Also, taste varies? I was also in my late 20s when I saw Buffy and late 30s when I watched Veronica Mars. Buffy was a bit more relatable, and unlike Veronica Mars - Buffy is supernatural dark fantasy, Veronica Mars is hyper-realistic teen noir.

I do however highly recommend Etoile.
